Excessive coolant leakage may indicate the need to
replace the water pump seal. For the removal of
water pump and the installation of the water pump
and/or seals, refer to the Disassembly and Assembly
Manual for the engine or consult your Perkins dealer.
• Inspect the lubrication system for leaks at the front
crankshaft seal, the rear crankshaft seal, the oil
pan, the oil filters, and the valve cover.
• Inspect the fuel system for leaks. Look for loose
fuel line clamps and for loose fuel line tie-wraps.
• Inspect the piping for the air inlet system and the
elbows for cracks and for loose clamps. Ensure
that hoses and tubes are not contacting other
components.
• Inspect the alternator belt and the accessory drive
belts for cracks, breaks, and other damage.
Belts for multiple groove pulleys must be replaced as
matched sets. If only one belt is replaced, the belt will
carry more load than the belts that are not replaced.
The older belts are stretched. The additional load on
the new belt could cause the belt to break.
• Drain the water and the sediment from fuel tanks
daily to ensure that only clean fuel enters the fuel
system.
• Inspect the wiring and the wiring harnesses for
loose connections and for worn and frayed wires.
• Inspect the ground strap for a good connection
and for good condition.
• Inspect the ECM mounting and ground strap for a
good connection and for good condition.
• Disconnect any battery chargers that are not
protected against the current drain of the starting
motor. Check the condition and the electrolyte
level of the batteries, unless the engine is
equipped with a maintenance free battery.
• Check the condition of the gauges. Replace any
gauges that are cracked. Replace any gauge that
cannot be calibrated.
High-Pressure Fuel Lines
Contact with high pressure fuel may cause fluid
penetration and burn hazards. High pressure fuel
spray may cause a fire hazard. Failure to follow
these inspection, maintenance and service in-
structions may cause personal injury or death.
After the engine has stopped, you must wait for 10
minutes to allow the fuel pressure to be purged from
the high-pressure fuel lines before any service or
repair is performed on the engine fuel lines. If
necessary, perform minor adjustments. Repair any
leaks from the low-pressure fuel system and from the
cooling, lubrication, or air systems. Replace any high-
pressure fuel line that has leaked. Refer to
Disassembly and Assembly Manual, "Fuel Injection
Lines - Install".
If you inspect the engine in operation, always use the
proper inspection procedure to avoid a fluid
penetration hazard. Refer to Operation and
Maintenance Manual, "General hazard Information".
Visually inspect the high-pressure fuel lines for
damage or signs of fuel leakage. Replace any
damaged high-pressure fuel lines or high-pressure
fuel lines that have leaked.
Ensure that all clips on the high-pressure fuel lines
are in place and that the clips are not loose.
• Inspect the rest of the fuel system for leaks. Look
for loose fuel line clamps.
• Drain the water and the sediment from the fuel
tank daily to ensure that only clean fuel enters the
fuel system.
• Inspect the wiring and the wiring harnesses for
loose connections and for worn wires or frayed
wires. Check for any loose tie-wraps or missing
tie-wraps.
• Inspect the ground strap for a good connection
and for good condition.
• Disconnect any battery chargers that are not
protected against the current drain of the starting
motor. Check the condition and the electrolyte
level of the batteries, unless the engine is
equipped with a maintenance free battery.
• Check the condition of the gauges. Replace any
gauges that are cracked. Replace any gauge that
cannot be calibrated.
Aftertreatment System
Check the condition of the coolant lines, Diesel
Exhaust Fluid (DEF) lines, and electrical
connections. Check that all clamps, clips, and tie-
wraps are secure and in good condition. Check that
the DEF filler cap is secure and that the cap is clean
and free from dirt.
Check the level of DEF in the tank is adequate for
operational purpose, if necessary fill the DEF tank.
